4. Avoid running on sidewalks, concrete, grass, or sand surfaces.


where the hell am i suppose to run then? lol... anyways when i was little i would wear these knee brace like the one forest gump had because my legs would face slightly to the side but it was fixed... but i noticed when i run instead of running with my feet straight and flat on the ground i run more with like the outer side of my feet. so i wonder if i can get that fixed or what?
